Thanks.  Even with your problem solved in the meantime, I would like to
know whether there is a bug in Automake to be fixed.  I cannot reproduce
the issue with the information you provided yet.

Which make version are you using?  Maybe handling of $* changed between
versions, and that causes the issues.

Can you send (off-list, gzip'ed) the Makefile that causes the failure?
I assume you are not using subdir-objects?  (I think your make output
already shows that.)

Please update to at least 1.10.3, preferably 1.11.1, in order to avoid a
security-related issue with 'make dist'.

Well, 'make distcheck' should be able to tell you whether what you chose
works with a read-only source tree.

OK, that looks sane.

Thanks,
